Column customization doesn't work for columns spanning relationships

[razagilani]

My datatable options are listed below:

 datatable_options = {
        'columns': [
            ("Project" , 'item__project'),
            ("Barcode" , 'item__barcode'),
            ("User", 'user__username'),
            'Duration',
            ("Items" , 'pagesDone'),
            ("Comments" , 'comments'),
            ("Task Completed" , 'operationComplete'),
            ("Pages Per Hour" , 'Rate'),
            ("Item Type" , 'item__itemType'),
            ("Task Type" ,'task'),
            ("Start Date", 'startTime'),
            'endTime',
        ],

 def get_column_Project_data(self, instance, *args, **kwargs):
        return  "<a>{}</a>".format(self.item__project)

after adding the above function to modify the output of Project column, the rendered data table contains no data.

@tiliv Can you please look into it. Thanks.

Just to confirm, is it a typo that you refer to self.item__project instead of instance.item__project?

[razagilani]

I have tried both with no luck

[tiliv]

Also, is it an issue that you are referring to instance.item__project instead of instance.item.project?

[razagilani]

Thanks, that was the issue.
